Itching of the vulva in summer may be caused by hot weather and humidity in the vulva. The most common causes are eczema of the vulva and vaginal inflammation. Vulvar eczema can be manifested as vulvar peeling or small papules on the vulva with a red color. You can apply ointments for eczema, such as skin relaxation ointment and trimethoprim ointment, which contain hormones and will get better soon after using them. However, vulvar eczema is very easy to recur, so you must pay attention to wearing cotton, breathable underwear, do not eat spicy food, do not eat seafood. If it is caused by vaginitis, the itching is caused by the increased vaginal secretions caused by vaginitis, which stimulates the vulva.
